My current major work is development of virtualization nodes (routers).
This is part of a research project on "New Generation Networks"
conducted by NICT.
I am also interested in
developing a new voice-communication medium called
voiscape, which can be more widely used than telephone or conference systems.
My work until fiscal year of 2001 was on active networks
(computing networks), policy-based networking, and
internet QoS (quality of service). Until around March 1999, I have been
studying and developing methods for searching and reorganizing
information placed on the Internet, e.g., WWW or online encyclopaedia,
especially on
"thematic search" / "axis-specified search".
I believe my lifework that connects most of the above researches is "fusion of analog
and digital", or "fusion of symbols and subsymbols".
These research-related information can be accessed through
"research themes overview" or
"research topics".
My paper list is in "paper summary".
Recently, I started a blog.
This blog contains information not limited to my research, but it contains much less
information than the Japanese version.
In addition, I supply East Japan Earthquake Support Information Blog (in Japanese), the Great
Hanshin Earthquake Page (in Japanese), and
the Great Hanshin (Kobe) Earthquake Page (in English, but most links are dead).

My Current and Past Research-themes (reverse order)

Development of network virtualization platform, which consists of programmable network nodes and which enables creation of virtual networks that is not restricted by conventional protocols such as IP or Ethernet.
New generation networks are studied on this platform.
